Description
Adjoint sensitivity is a valuable tool in diagnosing how specific attributes of a numerical weather prediction model state contribute to high-impact synoptic weather events. Previous studies focus on how changing individual model variables leads to the change at the final forecast state. The development of sensitivity to potential vorticity (PV) combines the sensitivity gradient to horizontal winds and to temperature and introduces “PV thinking” into the adjoint framework.
